Applications Airports Border check points Customs Government facilities Military bases Seaports Key Features The Portal has a state of the art Dual energy 7.5 MeV which is utilised for screening sea freight containers and truck trailers. The truck cab is not scanned, the system is ideal for use at container ports where the truck cab does not require screening. Note: The system is not suitable for screening box vans etc. Trucks drive through the scanner under their own power, allowing a high throughput of vehicles. Truck & 40 Sea freight container 30 per hour, Truck & 20 Sea freight container 60 per hour. The system has an automatic 3 colour coding for materials separation, providing distinguishing between organic, nonorganic and metal materials. This feature assists the operator to detect contraband, explosives, narcotics and weapons. The system can be easily relocated by a standard container truck. and re-commissioned by trained engineers typically within a 72 hour period The system requires a relatively small ground surface without special requirements for additional infrastructure. Radiation safety: The system uses low radiation dose technologies together with safety systems to provide a safe scanning system for vehicle drivers, system operators and bystanders Westminster Group Plc, Westminster House, Blacklocks Hill, Banbury, Oxfordshire, OX17 2BS, United Kingdom Page 1 of 12
System Components X-Ray Generator and Detector Modules a. X-Ray Generator Module b. Detector Module X-Ray Generator Internal Layout The 7.5 MeV X-ray dual-energy generates short X-ray pulses, with a maximum photon energy of 7.5 MeV. It is enclosed within radiation shielding with a slit-collimator that produces a narrow fan-shaped X-ray beam with the radiation angle of about 50º and the width not less than 2 mm. The radiation shielding of the accelerator and the collimator ensure a low-level dosage rate of not more than 0.5 μsv/h on average at the edge of the controlled exclusion zone. The beam orientation is adjusted remotely by the operator in the control room, the accelerator and collimator in the shielded case are mounted on the special platform with the electromechanical drives for finite adjustment. If the system exceeds the pre-set threshold dosage rate an audio-video and light alarms will activate and the system will automatically shut down. The X-ray assembly unit is provided with an air cooling system to sustain a pre-set operating temperature.

Computer Control System The schematic diagram below provides an overview of the system layout. The Computer system is located in the Control cabin and includes the following:- Control software Check-in workstation together with a Manifest Scanner Database workstation server, storing and administering access to images Review image workstations together with an image printer The computer system has been designed encompassing connectivity, security and openness for authorised access. The workstations are connected via a secure local network, there is a connection capability to external networks. Option - Remote Review Image Workstation and safe remote access to the server data is available.

The Radiation Safety System provides protection from x-ray radiation to drivers within the exclusion area and system operators and the general public outside of the exclusion area. The exclusion area is defined by the following safety requirement:- The ionising radiation dose outside the exclusion area shall not exceed 0.5 μsv on average in any one hour of system operation. The accumulated annual dose will not exceed the permissible limit of 1 msv (ICRP 2007), provided that no person is exposed to radiation more than 2,000 hours during a year (standard duty schedule) Components of Radiation Safety System 1. Radiation dosimeter 2. Audio and visual alarms 3. Optional Infrared exclusion perimeter control system 4. Intercom system 5. CCTV system 6. Sensors to locate the position of the inspected vehicle 7.
